Like the last gun I purchased I received no guidance on how to set this gun up in the package. With the last gun I wasted all kinds of time on the internet trying to find a video on how to set the FPS. I shouldn't have to call especially after business hours or on days off. With this gun it took me too much time to find how to get the battery in the grip. I finally found the tiny blended in screw to remove the grip. The FPS adjustment I speculate is like my last gun. The more irritating lack of guidance is the tracer unit. I wasted time looking on the internet for information or a video on how to turn on this tracer unit that was listed with this gun. I thought I found information that you had to shake the tracer unit to turn it on and put a pen or pencil in it to turn it off. But no that's not the unit I have. Now I have to call airsoft junkies to find out how to turn this thing on and off. Just because you people work with these guns all the time doesn't mean the customers are familiar with them. It'd be good for the customer to receive in the packaging an instruction sheet on how to use the components or at least video links that we can go online to look at how to operate some of these components.
